Description
Technical field:
The utility model relates to a kind of slag storehouse more particularly to a kind of slag storehouse systems of novel weighing type level measurement.
Background technique:
Thermal power plant slag storehouse system is the equipment of transfer, storage for slag removing system, it, which is received, fishes out slag from scraper plate
The bottom ash that machine conveying comes, is transported outward after of short duration storage by the dedicated drawing slag car.Slag storehouse system generally configures two slag storehouses, when
It piles rear system and is switched to another slag storehouse slagging in one slag storehouse.The material position device of slag storehouse measurement at present generally uses ultrasonic wave material position
Meter or radar level gauge, and it is inaccurate often to will appear slag storehouse level measurement in actual use cause slag storehouse to overflow slag, make
Submerged slag conveyor crosses torque tripping, can not normally convey deslagging, unit load limit can be made when serious, influence unit normal power generation.
Slag silometer is caused to be not allowed have many-sided reason, on the one hand since submerged slag conveyor conveying deslagging is generally wet slag, into slag
A large amount of steam can be generated behind storehouse, so that level-sensing device is popped one's head in and are glued water, influence level-sensing device measurement accuracy；On the other hand since slag storehouse is opening
Design, so level-sensing device can not be installed among slag storehouse, can only be installed on slag bulkhead, measured result cannot really reflect reality
Border controlling level.It is not able to satisfy actual operating mode and wants so measuring this mode of slag storehouse material position by traditional level-sensing device
It asks.
Utility model content:
The purpose of this utility model is to provide a kind of slag storehouse systems of novel weighing type level measurement.
The utility model is implemented by following technical solution: a kind of slag storehouse system of novel weighing type level measurement comprising

Secondary, verification while, carries out adjustment record, and the weighing slag storehouse system after verification is qualified can normally come into operation；
Slag storehouse receives from the next boiler slag removal of submerged slag conveyor conveying and its weight of material is all transmitted to positioned at slag
On multiple weighing sensors between storehouse and support frame.The elastomer of sensor internal is deformed because of stress, interior patches electricity
Resistance value changes, and exports and be weighed the weight of material under the action of for bridge voltage (EXC+/EXC- is also driving voltage)
Proportional direct current millivolt voltage signal (SIG+/SIG-), the weighed terminal box of the voltage signal are passed by shielded cable
It is sent to the PLC controller of matching.Voltage signal, through amplification, conversion inside PLC controller, circuit conversion at corresponding weight (or
Height of materials, that is, material position) show value, while its weight is shown by display.
High material alarming value and high high charge level trip value are set by PLC controller, material position reaches high charge level alarm when slag storehouse
Combined aural and visual alarm is controlled when value and issues alarm signal prompting operations staff note that if submerged slag conveyor also continues slag input, is reached
When high high charge level trip value, PLC controller, which issues submerged slag conveyor cascading trip signal, makes submerged slag conveyor system trip, prevents
Overflow slag in slag storehouse, while combined aural and visual alarm issues alarm signal, and operations staff is reminded to take slagging measure in time.In slagging process
In, it, can be to drawing the slag car to quantify slagging, according to difference by the automatic control of weighing sensor, controller and driving motor
